HIGHLIGHTS FOR 1994 



The Poplar River Power Station completed its eleventh full year of operation in 1 994. The two 300- 

 megawatt coal-fired units generated 4 397 600 gross megawatt-hours (MW/h) of electricity. In 1 994, 

 the average capacity factor for Unit No. 1 was 80.5 percent and the average capacity factor for Unit 

 No. 2 was 89.2 percent. 



Monitoring information collected in both Canada and the United States during 1994 was exchanged 

 in the spring of 1995. In general, the sampling locations, frequency of collection, and parameters 

 met the requirements identified in the 1994 Technical Monitoring Schedules set forth In the 1993 

 annual report. 



The March to October recorded flow of the Poplar River at International Boundary for 1994 was 

 14 500 cubic decametres (dam^) which was 144 percent of the 1931 to 1990 median seasonal flow. 

 The 1994 recorded flow volume of the East Poplar River at International Boundary was 2 420 dam^. 

 This volume is 76 percent of the median annual flow since completion of Morrison Dam in 1975. The 

 on-demand release, in accordance with the apportionment recommendations of the International 

 Joint Commission (IJC), entitled Montana to 370 dam^ for 1993-94 to be delivered between May 1 

 and May 30, 1 994. A volume of 391 dam^ was delivered during this period. 



The 5-year moving flow-weighted concentrations of total dissolved solids for the East Poplar River at 

 International Boundary which reached 975 milligrams per liter in 1993 declined to 966 milligrams per 

 liter in 1994. The slight reduction was a result of spring runoff in 1994. Even though there was a 

 slight decrease in the 5-year moving flow-weighted concentrations for total dissolved solids for 1994, 

 the upward trend that has occured since 1987 will probably continue if surface-water runoff 

 continues to be below average.
